Hey folks, I'm starting out on the path of iOS Development and am currently in the process of acquiring reading materials and signing up to blogs and forums to get started. I found this recommended reading list: http://ios-blog.co.uk/resources/recommended-reading-ios/ searching twitter believe it or not. It covers iOS4 and 5 The two questions I suppose I would like to know is: 1) Would it be worth reading about iOS4 first? 2) Is there any books that are on this list, or infact even not you can recommend? Thanks guys, Much appreciated.
